Sorry, not a fan of anyone trying to upsell their work here.
There are plenty of sites for that. We are the folks who make the things, not the folks who buy the things 
We welcome members to post a link to their portfolio if they would like to show off their work. We also have a section for work to be critiqued. If you would like to start a thread for posting images to show off your skills with NO pricing involved, that is fine as well. However as it’s been mentioned, you may not get many participants as most have NDA’s with their clients. We used to have a classified section for potential clients or designers looking for work and it was always more of a pain than it was worth.
That’s my take on it
